Glacier Studies of the McCall Glacier, Alaska
Describes in detail this glacier in the Romanzof Mts., Brooks Range, northern Alaska, studied during the McCall Glacier Project, 1957-58. The crescent-shaped body of ice, approx. 8 km long, 640 m wide and 1,450 m high, has three cirques and a well defined drainage basin. From the confluence of the c...
